Description

Especially «on ships» o the tree-lined trees are often difficult to tighten and Loosening the mats in machines and machine parts · These mats can sometimes have very large dimensions and it was rumored that you would get old with a heavy hammer the handle of the Matter-adapted soleplate must, so that the tightening becomes strong enough · Often but then tighten the excessively strong what the bit formation Clay bite in the machine, for example in that Cylinder head of the same, with see leads tightening and loosening clay nuts using pneumatically driven viethammers to remove their dead 3ohlagorgane on the outer bath of the Sobüsselhaadgrlffes attack·

The present invention is based on the last-mentioned idea and relates to a solo tool, daa sas adapted to one of the mother or the like Sohlassel and a pneumatic hammer which is used to turn it

fork-shaped and with its two legs it grips both sides of the soleplate arm · This becomes daa The tool is massive and can withstand considerable stress

According to another embodiment, the holder legs each have an aohsial hole with an in the longitudinal direction of the same against the action of a buffer spring movable piston provided · The Sohltieselarm passing lobe is carried with its sins τοη the two pistons · By this buffer device the tool will work very smoothly both at the beginning of tightening »the nut, if no significant Resistance το r hand en is like at the end of the reading, if the resistance is very high

If after elmr other suitable carrion form the invention, the two Sohlagkanten of the Sehlüsselarmee si oh mainly extend along the same arc with the center in the middle of the steering axis (of the Sapfene), the sole agorgan of the tool, after the same thing worked on one edge of the sole after the holder with the jam has been swiveled half a turn in relation to the 8 <thlfLsselarm, daeu be brought against the other sole edge sum

The one in Pig. 1 shown key 1 is a so-called Combination wrench »from which an arm 2 extends radially. This is mainly circular in shape Striking edges 3 »4 with the center point in the middle section of Army 2. Duron this section runs a tenon 5, around which a holder 6 for a pneumatically driven anti-halyard 7 can be pivoted. The holder 6 consists of two plates held together by expander bolts 8 It engages at one end with two legs 10 in the form of a fork on both sides of the Sohlüsselarmes 2. On the opposite one At the end, the plates 9 grip the head 11 of the riveting hammer 7, so that it is held securely on the holder

So that the pin 5 should not hit the plug during this movement, the ends of the pin 5 are laterally in piston 16, axially movable in the relevant bore 14, inserted and between the plug and the end of the one in question Pistons 16 have been clamped into the bores 14 springs 17, which serve as buffer the springs 17 rerhindem, that the pistons 16 hit the plug 15 after the sole element 12 has actuated the sole arm 2

Swiaohen the bottom 18 of the bores 14 and the adjacent end of the piston 16 in question arises Moving it in the opposite direction creates an air cushion that also acts as a buffer when moving of the lobe 5 and thus also of the key army 2 in the opposite direction or during the movement of the Holder 6 in the base alignment

If the chuck 19 is to be tightened, assuming that the nut has a pike thread, the hammer 7 with the holder 6 is pivoted half a turn in the direction of the arrow 20 in the counterclockwise direction, so that the hammer 12 then moves to the The striking edge 3 of the key arm 2 will work

It is the embodiment shown and described To be regarded only as an example, and the justification both the riveting hammer 7, the holder 6 and the key 1 can be different in the context of the following Claims are changed · The holder 6 can optionally be made in a single, fork-shaped piece.
